The Ants
حَتَّىٰٓ إِذَا جَآءُو قَالَ أَكَذَّبْتُم بِـَٔايَـٰتِى وَلَمْ تُحِيطُوا۟ بِهَا عِلْمًا أَمَّاذَا كُنتُمْ تَعْمَلُونَ
Until, when they arrive [at the place of Judgement], He will say, "Did you deny My signs while you encompassed them not in knowledge, or what [was it that] you were doing?"

۞ وَإِذَا وَقَعَ ٱلْقَوْلُ عَلَيْهِمْ أَخْرَجْنَا لَهُمْ دَآبَّةً مِّنَ ٱلْأَرْضِ تُكَلِّمُهُمْ أَنَّ ٱلنَّاسَ كَانُوا۟ بِـَٔايَـٰتِنَا لَا يُوقِنُونَ
And when the word befalls them, We will bring forth for them a creature from the earth speaking to them, [saying] that the people were, of Our verses, not certain [in faith].
وَيَوْمَ نَحْشُرُ مِن كُلِّ أُمَّةٍ فَوْجًا مِّمَّن يُكَذِّبُ بِـَٔايَـٰتِنَا فَهُمْ يُوزَعُونَ
And [warn of] the Day when We will gather from every nation a company of those who deny Our signs, and they will be [driven] in rows
وَوَقَعَ ٱلْقَوْلُ عَلَيْهِم بِمَا ظَلَمُوا۟ فَهُمْ لَا يَنطِقُونَ
And the decree will befall them for the wrong they did, and they will not [be able to] speak.
أَلَمْ يَرَوْا۟ أَنَّا جَعَلْنَا ٱلَّيْلَ لِيَسْكُنُوا۟ فِيهِ وَٱلنَّهَارَ مُبْصِرًا ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يُؤْمِنُونَ
Do they not see that We made the night that they may rest therein and the day giving sight? Indeed in that are signs for a people who believe.
